HINGE.

SPECIFICATION forming part of Letters Patent No. 721,721, dated March 3,1903. Application filed May 23, 1$l02. Serial No. 108,640. (No model.)

In hinges of the character referred to and to which this inventionrelates there is a backing or reinforce plate which issecured to thewall by ordinary screws, and projecting from this plate is a shankcarrying toward its outer end a pintle upon which the companion leaf ormember of the hinge is mounted so as to swing.

The main objects of my invention are to improve the construction of sucha hinge, to increase the strength and rigidity of the supporting plateor backing, and to so secure the parts together as to give great andincreased strength over what has been heretofore employed. i i

Another object of this invention is to so assemble the parts that whenthe hinge is placed against a flat wall the backing-plate will restsnugly against said wall and so secure afirm seat or bearing, thuspreventing the tilting of the backing-plate and the workingout of thescrews or other fastening devices employed as the means of connectionbetween the wall and said backing-plate. w

In the drawings, Figure l is a perspective view of that part of a hingein which the improvement is made. Fig. 2 is a vertical section of thehinge part shown in Fig. 1. Fig. 3 is a horizontal section. Fig. 4 is afront View of the hinge as applied.

A is a backing-plate of any suitable outline. As shown, thebacking-plate A is formed of a thin sheet of metal having parallel sidesand similarly-shaped ends. This permits the successive production ofthese backing-plates from a continuous strip of metal without waste.

B is a pintle arranged substantially in line with the backing-plate andparallel'thereto. The pintle B is secured to the backing-plate by meansof a shank, which, in the form shown, is a strip of metal bent in themiddle and closely embracing the lower end of the pintle, so as tosecurelyhold the same. The double ends of the strip are arranged. closetogether to form the shank D. The end of the shank D is narrowed bynotching the upper and lower edges. These notches form short shoulders dd. In the backing-plate A a corrugation a is formed, providing a cavityon the rear side of said backing-plate, for the to receive the upset endof the shank D when the parts are assembled.

The parts are assembled as follows: A hole is formed in thebacking-plate A of the proper size to receivethe narrowed end of theshank D. The length of this narrowed end of the shank is greater thanthe thickness of the metal constituting the backing-plate. The parts areput together so that the shoulders d 01 rest against the outer surfaceof the backing-plate Aupon' the elevated surface formed by thecorrugation a. When the parts are thus assembled, it will be seen thatthe eX- treme end of the shank, whether or not the shank is in one ortwo thicknesses of metal, projects through the backing-plate. Thatportion of the shank D:projecting through the backing-plate A is thenupset andheaded down into the pocket formed by-the corrugation a and sothat it will lie substantially flush with the general plane of the rearsurface of said plate. The device thus constructed will have greatstrength at the vulnerable point where the heaviest strains are applied.It is not essential that the corrugation should extend throughout thegreater portion of the backing-plate; butitis simply essential that itshould extend throughout that portion where the connection of the shankand plate is joined and where the twist and strain are directly applied.The device thus formed can be secured fiatwise against the woodwork, andpractically the entire rear of the backing-plate will make a smoothunbroken contact therewith, as would not be the case were the head ofthe shank permitted to project beyond said rear surface.

E is a companion leaf, which is pivoted on the pintle B. The companionleaf E may be secured to the blind in any desired mannerfor example, asshown in Fig. 4-while the backing-plate A is secured to the Windowcasingadjacent thereto.

What I claim is-- 1. A hinge member comprising a backingplate having acorrugation therein forming a pocket at the rear side thereof, anopening through the corrugated portion of said backing-plate, apintle-supporting shank passing through the opening in said plate, theextreme ends of said pintle-supporting shank being upset and containedwithin the pocket at the rear side of the backing-plate, su bstantiallyas described.

2. A hinge member comprising a plate having a corrugation thereinforming a recess at the rear side thereof, and an opening through thecorrugated portion of said plate, a pintlesupporting shank adapted topass through said opening in said plate, that portion of the shankprojecting through said plate being riveted or upset and containedwithin the recess at the rear side of said plate.

3. A hinge-hook comprising in its construction a metal plate, an armupset within a slot formed in said plate, a pintle held by said arm,said plate being recessed at its rear face to bring said arm out ofcontact with the surface to which the hinge-hook may be applied,substantially as described.
